COMBINATION-TOOL.

SPECIFICATION forming part of Letters Patent No. 268,560, dated December 5, 1882.

Application led April 10,1882. (No model.)

To all whom it may concern:

Be it known that we, ELI SMITH and JAMES DUGKWORTH, citizens of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvementsin Combination-Tools, of which the following is a specification.

This device consists of an adjustable bevel and miter, and also forms a tool having stops to the blade at right angles and at forty-five degrees to the straight edge of the stock, the object oi' our invention being to provide an improved tool of this class having a fixed stop in its stock, whereby the blade is brought to a position at right angles to the stock, and

having a movable stop on the latter, adapted to be swung across the blade-channel therein, in order to stop the blade at an angle of fortyve degrees to said stock, and to .be turned back to leave said channel open on one'side, so that the blade may be received in the stock in aline therewith, and to provide easily-operated and efficient clamping devices to secure said blade in ,any desired position.

In the drawings, Figure I is a view of the complete device in perspective. Fig. II is a sectional view; Fig. III, a side view, and Fig. IV a detail view.

The stock D is formed of two sections, held in immediate contact at the rear end of the tool by the screws d d, and at a sufficient interval apart at the front end of the tool toad- A mit of the movement of the blade between the sections and in .the channel b by the screwstud H. lIhe stud H, having its `head coun- .tersunk in one section of the stock and having its end screwed intothe other section, passes iutermediately through the slotg of the blade B, and so forms a pivot-stud for the blade.

Loose upon the pivot-stud H, and arranged to have one side bear again-sta corresponding side of the blade, is a washer, G, and adapted to come against the opposite side ofthe washer C from that in4 contact with the blade, is the conical head of a screw-stem, I.

The operation of the mechanism is as follows By the advancement ofthe cone under the loose washer bearing against the loose blade, the washer is forced upon the stnd,rig-

| idly uniting the sections of the stock, to clamp the blade to one section.

In detail the cone-*screw I has its nut, as shown in Fig. II, in section, and has its point aligned to pass over the corner of the washer, While its stem is prolonged to extend to the outside of the rear of the tool, where it is provided with the convenientoperating-handle m.

The pivot-stud H is' provided with a transverse hole, h, to admit of the movement of the 6c point of the cone past the rim of the washer, and'in practice we form this hole of snfiicient size to permit a rotary play of the stud in adjustment, while still leaving interval for receiving the point of the screw I.

The washer C is allowed movement from the blade when released by the screw I by a Countersink in the section from which it moves, as shown in Fig. II.

It will be seen that in this mechanism, by 7o a slight movement of stud H, the other parts can be so adjusted as to canse the slightest movement ot' screw-stein I to cause the blade to be clamped, and that by the movement of said stud the wear of the parts forming the clamp can be easily taken up.'

In order to permit the tool to be quickly and with certainty converted into a try square, the stop W is arranged transversely across the slit b from section to section, and, beingy 8o permanently secured to one, is received in a dovetail in the other, by means of which the sections may move in4 receiving adjustment through the stud H. While the blade is thus stopped on one side of the stock it is free to be moved to any angle upon the other, and to stop it at the frequently-required angle of forty-rive degrees a movable stop, V, is formed, as shown in Fig. III, by a hinged piece recessed in the stock to preserve the straight 9o edge, and capable of being easily moved to obstruct the blade or give it free play.

Now, having `described our invention, what We claim isl. In combination, the stock D, having the channel b between its sides, the blade B, having the slot g therein, the stud H, rigidly tixed in said stock` and passing through said slot in blade B, the fixed stop W, set aero/ss said channel b on oneedge ot' said stock,thewasher rco c, loose on stud H, and the point I, substantially as set forth.

2. In combination, lhe stock D, having the channel b between its sides, the

ing the slot, g therein, the stud H, rigidly fixed in said stock and passing through said slot; in

blade B, the hinged stop V, ada across said channel b on One ed screw-stem stock, the Washer c, loose on stud H, andthe pointed screw-stern I, substantially as set forth. [o
